You would be happy to know we have about 7 signs. One with the prohibited items list. One with the Federal law about firearms in airports( big big sign).

Then 5 that tell you about film and your opitions, another telling you to remove your laptop, another telling you to place at metal objects on your person in your carryon or a provided bin. And the last two have to do with jackets and pacemakers.

But like I said, most passengers, like as many as about 80% dont take the time to read them and come up and ask us what they need to do, forcing us to yell, hehe are checkpoint doesnt carry sound to well.
